Windows XP Startup

EDITORS NOTE 05/10/2009: Benchmark Reviews has re-tested the OCZ Vertex with the latest v1.10 firmware, which includes TRIM support, and the resulting performance was generally identical to the previous firmware. Please remember that TRIM is a Windows 7 supported feature, and does not improve performance on Windows XP or Vista Operating Systesm.

After several SSD product reviews in which I recorded Windows XP startup time data, I have repeatedly omitted my results from the article for lack of enough comparison data. In all honesty, I cannot make this an interesting subject. Most of you reading this article have already watched the video of a Windows computer starting up in mere seconds when it used a Solid State Drive, so it wouldn't be very exciting to show it again. Instead, I have recorded the length of time it took for my Dell Inspiron 6400 notebook computer to startup with each drive. Here are the specifications on the notebook:

  • Dell Inspiron 6400 Notebook
  • Intel Core Duo T2300 @ 1.66 GHz
  • 2GB DDR2 667 MHz System Memory
  • Windows XP Professional SP3 (identical image cloned to each drive)

This "test" is going to be useful to laptop computer users only, primarily because I did not test the desktop hard drives. The only hard drive included was the high-performance 7200 RPM Hitachi Travelstar 7K100, which recorded a 28-second load time from the moment I pressed the power button to the moment the Windows Login screen was displayed.

The primary purpose of this test was to demonstrate that a Solid State Drive could in fact cut the Windows load time in half, but there are other factors to consider. It's important to note that this particular Dell notebook consumes almost 11 seconds on the BIOS pre-loading and POST (Power-On Self Test) routine prior to actually beginning to load Microsoft Windows XP, so it's not realistic to think that my results would match another system identically.

Drive Hardware

In the next section, I begin to summarize my final thoughts on the OCZ Vertex series SSD as well as Solid State Drives in general. Please continue on to see what I think of SSD technology in todays consumer market.

I'm always wary of Mbps(bits) and MB(bytes), too many people use them interchangably. The Ads on the same page for this product say "250MB" not bits, so what is the Atto 249 MBps maximum read bandwidth??? bizarre?

Anthony, typically Mbps (Megabits) refers to a transfer speed whereas MBs refer to a capacity. Whether ignorant people use them interchangeably or not, using this guideline you should always be able to figure out which it is. :)

I'm not exactly clear which side of the argument you're on here, Marko. Read up on the specifications for any SSD product, and you'll see their bandwidth speed represented as MB/s.

MB when used in advertised capacity is not Megabytes, it's Million Bytes. Bytes or Bits will be denoted by B or b respectively. When the vendor advertise 250MB, it means 250 Million Bytes which is approx to 244.14 Mega Bytes. This 244.14 is RAW Megabytes and have not included partitioning and other possible overhead used in the system which may yield lower capacity than 244.14 Megabytes.

When used on the bandwidth, make sure you fully understand what the bandwidth measures. In different network or cable setup, the bandwidth could be shared and a single device do not usually get that kind of bandwidth on average. On network, typically vendors means Megabytes when they denote MB unless otherwise denoted using fineprints, but the usual price is using Megabits which looks a lot better on paper.

# RAID-0 Setuptypoknig 2010-05-10 09:52
How exactly did you have your RAID-0 setup during this test? For instance, were you using the Intel Matrix Storage Manager or some other method?

# Intel ICH10Olin Coles 2010-05-10 15:11
RAID-0 was built using the motherboard's Intel ICH10 controller.

What stripe size was used in the RAID 0 setup and why?

# 128KB Stripe SizeOlin Coles 2010-05-12 08:49
This articles used a 128KB stripe size, which is the largest the Intel ICH10 controller allows for RAID-0 sets.

# Benchmarking A Bigger RAID 0 Arraytypoknig 2010-06-08 22:06
Hi, I have been running the same benchmarks you ran on my RAID 0 array which has 3 120GB OCZ Vertex drives compared to the 2 used in this benchmark. My results have not even been close to what I thought I would be getting after reading this review. I have posted some info about my results here:

##overclock.net/benchmarking-software-discussion/750979-benchmarking-3-120gb-ocz-vertex-ssds.html

Maybe you can take a look at my stuff and tell me why my linear read in Everest does not produce a flat line like yours (I realize I used 512MB block size, but the 1MB block size produced identical results), and why my numbers are so much lower when they should be higher. I have also ran the benchmarks without an OS (or any data) on the array at all, and the results are very similar. Any thoughts?

# Partition alignmentOlin Coles 2010-06-14 19:43
I'm betting that our results are higher because of drive conditioning: partition alignment, diskpart clean all, secure erase, etc. Since TRIM doesn't always pass through to RAID arrays, used drives will produce lower performance results.

# sanitary erasetypoknig 2010-11-27 21:23
I have had this problem fixed for quite some time now. If you go to the link I provided in my last comment you will see that using sanitary erase did trick for me... so as you said, "drive conditioning" was my problem. To keep my drives as clean as possible I use the "Wipe Free Space" feature of CCleaner. Does the same thing as wiper.exe but it works when drives are in RAID (unlike wiper.exe).

Samsung K9HCG08U1M-PCB00 is flash memory, not DRAM... this is why we call it an SSD

# 4-drive RAID 0Remo 2010-12-23 08:42
Mr Coles, do you have any idea how would a 4 SSD in RAID-0 perform? Would you use it as the boot drive in a windows 7 system?

# RE: 4-drive RAID 0Olin Coles 2010-12-23 08:44
You should look into the OCZ RevoDrive 2 PCI-Express SSDs, which fit four SSDs into RAID-0 on one board. Our review is here:

# RE: RE: 4-drive RAID 0Remo 2010-12-23 08:57
I definitely will look for it. But, how much gain in performance would you expect when upgrading from a 2-drive raid-0 to a 4-drive raid-0?
